Make a date with Wedding Band’

Here are two things you don’t see very often: an hourlong television comedy and a scripted sitcom on Saturday night that is worth watching.

“Wedding Band,” which made its debut Saturday on TBS, is both, at least if we can presume that the Saturday night television audience isn’t expecting intellectual rigor and doesn’t mind ribald content. If nothing else, tune in to this show and you’ll end up hoping that the group of the title plays the next wedding you are dragged to, especially if it’s your own.

The series chronicles the exploits of Mother of the Bride, a hard-rocking wedding band in Seattle with a tendency toward misbehavior but also a keen understanding of its place in the universe. In the pilot the three longstanding band members — Tommy (Brian Austin Green), Eddie (Peter Cambor) and Barry (Derek Miller) — are breaking in a new guy, Stevie (Harold Perrineau), which gives them a chance to explain some of the finer points of wedding band-ness.

It’s the band’s job, they tell him, to identify the most pitiful-looking nerd in the crowd and make sure he has the time of his life by inviting him up to help with the vocals on some song. It’s also the band’s job to make sure the right woman catches the bouquet. Oh, and if you want to score with a female member of the crowd, Stevie’s bandmates advise him, look for the woman who is singing along the loudest to “I Will Survive.”

Stevie and Tommy succeed early and often with the opposite sex, while Eddie is a family man with children, and Barry is a Jack Black sort of man-boy. The pilot episode felt a bit obligatory — the band finds itself playing at the wedding of Tommy’s ex-girlfriend — but things branch out in subsequent installments.

In the second episode, which features Megan Fox as a guest star, the band clashes with some sci-fi geeks, to ridiculous effect. And while it’s no surprise where Episode 3 leads the guys — weddings mean bachelor parties, which mean strip clubs — the “Wedding Band” foray into that universe is a refreshingly skewed variation of the strip-club-scene cliché (perhaps because the episode was written by a woman, Elizabeth Tippet).

The series has assorted female characters, but this is a male-centered world, akin to the raunchy FX comedies “The League” and “It’s Always Sunny in Philadelphia.” The interactions among the core four men are the key, and the likable actors playing them make most of the scenes work. Feel free to start your own debate about which Mother of the Bride member equals which Beatle, or which Monkee, or whatever.

As in “The Monkees,” there is a fair amount of music in this show, and it’s an eclectic assortment. This bizarrely versatile band can shake the walls with plain old rock ’n’ roll, but it’s at its best when playing songs the way you don’t remember them, a demented “Glee.” Keep an eye out for Stevie and Barry’s cello-and-glockenspiel version of “West End Girls.” The Pet Shop Boys would be proud.
